The document presents a screening exercise that identified 26 NAMA concepts for Trinidad and Tobago across six UNFCCC sectors. It analyzes the country's high per-capita emissions driven by the petrochemical industry and proposes specific mitigation measures in energy, industry, transport, agriculture, forestry, and waste to support a transition to a low-carbon economy.

The document analyzes the divergent paths taken by Canada and Australia to mitigate greenhouse gas emissions. While Australia implemented a unified national carbon pricing system (transitioning from a carbon tax to cap-and-trade), Canada adopted a decentralized, sector-by-sector regulatory approach utilizing provincial equivalency agreements. The authors argue that Canada's fragmented system is likely to result in higher regulatory costs for emitters compared to Australia's streamlined national approach, although the actual emission reductions of both schemes remain uncertain.

The report analyzes the steel sector's transition to a low-carbon future, noting that while current carbon pricing (like the EU ETS) has had limited impact on plant location and investment, deeper emissions cuts will require breakthrough technologies such as carbon capture and storage (CCS). It emphasizes the need for collaborative research, development, demonstration, and deployment (RDD&D) and suggests a 'coalition of the willing' among major steel-producing nations to maintain competitiveness while decarbonizing.

The report finds that South African coal reserves earmarked for domestic use exceed the country's potential carbon budget through 2050, creating a risk of 'unburnable carbon' and stranded assets. It argues that current capital expenditure on developing new coal resources is incompatible with climate goals and urges investors to challenge the business models of coal miners.

The authors contend that natural gas cannot solve the climate problem without carbon capture and storage (CCS), as it only offers a 50 per cent carbon dioxide reduction relative to coal, assuming no methane leakage. Given that fossil fuels are projected to remain a major energy source to meet growing global demand, particularly in developing countries, the document asserts that large-scale CCS is essential for all fossil power. While post-combustion capture (PCC) is commercially available for natural gas plants and faces fewer technical hurdles than coal PCC, the authors warn that relying on cheap, unabated natural gas may delay the commercialization of CCS. They recommend stricter CO2 emission limits, expanded incentives for enhanced oil recovery, and increased governmental support to scale up CCS technology.

The study estimates that the Natura 2000 network stored approximately 9.6 billion tonnes of carbon in 2010, with a monetary value between €607 billion and €1,130 billion. Forest habitats are identified as the most significant carbon sinks. The authors compare a 'Policy ON' scenario (improving conservation status and expanding protected areas) against a 'Policy OFF' scenario (inaction), finding that active policy interventions could generate economic gains of 1.71% to 2.86% by 2020. Specifically, increasing protected forest area by 10% is projected to provide €16 to 23 billion more in immediate benefits than focusing solely on qualitative site improvement.

Ecuador's Socio Bosque programme provides annual per-hectare payments to private and communal landholders who maintain forest cover. While not originally designed for REDD+, it supports Ecuador's climate strategy by reducing deforestation and increasing the resilience of the rural poor. After three years, the programme covered 881,933 hectares through 1,566 agreements, though it faces challenges regarding land titling and high monitoring costs.

The cement sector is a major global CO2 source, with emissions projected to reach 4.0 Gt by 2030. While emissions intensity is declining due to the adoption of best available technology (BAT) and alternative fuels, these gains are offset by rising production volumes, particularly in China. The report argues that current carbon pricing, such as the EU ETS, is insufficient to drive the breakthrough technologies needed for a low-carbon future, such as carbon capture and storage (CCS) and new low-carbon cement forms. It suggests that a combination of public-private financing, revised building standards, and Border Carbon Adjustments (BCAs) is necessary to prevent carbon leakage and incentivize deep decarbonization.

The document outlines a modelling case study using the DO3SE model to estimate ozone-induced reductions in carbon storage within European forest biomass for the years 2000 and 2040. It specifically examines the influence of climate, species-specific flux parameterisations, and soil water stress on these reductions, while comparing AOT40 and PODY estimates and exploring the link between ozone sensitivity and leaf morphology.

An open letter from Scientists for Global Responsibility to the UK Secretary of State for Energy and Climate Change arguing that the Draft Energy Bill and current energy policies are unambitious and biased toward the nuclear industry at the expense of renewables and energy efficiency.

The author argues that geologic carbon storage and hydraulic fracturing can safely coexist in the U.S., asserting that a Princeton study erroneously ignored the vertical separation (depth) between storage reservoirs and shale gas formations. The text emphasizes that multiple impermeable layers often separate these activities and that regulatory oversight and 3D geologic studies can mitigate risks. Additionally, it notes that U.S. storage capacity is vast, including offshore sites and depleted petroleum formations, meaning shale gas activity will not impede carbon capture and storage development.

The study finds that CCS deployment in Germany would lower spot market electricity prices and reduce imports from France, Belgium, and Poland, while increasing producer and consumer surpluses.

The Clean Air Task Force supports the EPA's proposed new source performance standards (NSPS) for fossil-fueled power plants, which would limit emissions to 1,000 lbs. of CO2 per megawatt-hour. The author asserts that carbon capture and sequestration (CCS) technology is currently available and cost-effective, enabling new coal plants to meet or exceed these standards. The document highlights existing commercial CCS projects and the potential for the enhanced oil recovery (EOR) industry to create commercial demand for captured anthropogenic CO2, providing a hedge against future emissions if natural gas prices rise.

The brief uses the Canadian Integrated Modelling System (CIMS) to evaluate proposed regulations requiring new or modified coal plants to meet a performance standard of 375 g CO2e/kWh. The analysis projects that these regulations would reduce electricity sector emissions by 5 million tonnes (Mt) in 2020 and 20 Mt by 2030, with an average cost of $26 per tonne of GHG reduced. The findings indicate that coal generation would be primarily displaced by natural gas turbines, which are expected to account for 77-78% of the replacement, while carbon capture and storage (CCS) and renewables would play smaller roles.

The 66th CDM Executive Board meeting established the 2012-2013 business plan and the 2012 Management Plan, which includes a commitment to assess improvements for demonstrating additionality in large-scale projects. The Board is transitioning to a risk-based approach for project registration to handle an expected surge in applications before 2012 year-end EU restrictions. Other key developments include the creation of a permanent working group for Carbon Capture and Storage (CCS) and ongoing debates regarding perverse incentives in nitric acid N2O abatement methodologies. Carbon Market Watch expressed concern over the risk-based approach and the lack of Board discussion regarding the price collapse of EU-ETS allowances and CDM credits.

The report examines how the DoD's unique capacity for end-to-end research, development, and procurement can be leveraged for energy innovation. It analyzes three case studies—gas turbines, alternative fuels, and soldier-portable power—and compares the innovation models of DARPA and ARPA-E. While the DoD is a powerful engine for technology, the report notes that its contributions to climate goals depend on the alignment of energy needs with the military's core security mission. It highlights the 'Installation Energy Test Bed' as a successful model for overcoming the 'Valley of Death' in technology commercialization.

The document critiques the application of carbon trading in Africa, asserting that the continent remains marginal to the global market. It highlights how the Clean Development Mechanism (CDM) creates perverse incentives, such as rewarding illegal gas flaring in Nigeria or subsidising fossil fuel dependence, while providing minimal financial benefit to local communities. The author argues that carbon offsets act as an 'avoided responsibility mechanism' for the global North and recommends shifting toward more just forms of climate finance.

The document reports on a side event at the 17th Conference of the Parties to the UNFCCC in Durban, where delegates and experts discussed the economic and environmental benefits of phasing out fossil fuel subsidies. It highlights the disparity between the US$100 billion Green Climate Fund and the US$400–600 billion in annual global fossil fuel subsidies. The report details the activities of the 'Friends of Fossil Fuel Subsidy Reform' group, the challenges of political economy in implementing reforms, and proposals to integrate subsidy reform into Nationally Appropriate Mitigation Actions (NAMAs) and the Rio+20 conference.

The author asserts that setting CO2 performance standards for coal-fired power plants is the primary environmental and energy policy priority for 2012, as these plants are the largest stationary sources of carbon dioxide. While the Mercury and Air Toxics Rule (MATS) and the Cross-State Air Pollution Rule (CSAPR) protect public health, they do not reduce carbon dioxide emissions. The document emphasizes that building new plants without carbon controls is unjustifiable and that such standards are necessary for the U.S. to meet its commitment of a 17 percent reduction in emissions below 2005 levels by 2020.

The document uses the POLES energy system model to assess how varying levels of economic growth and convergence between developed and developing nations affect the cost of climate stabilisation. It finds that limiting warming to 2°C is technically feasible and economically viable across all tested scenarios, with global abatement costs remaining below 2% of GDP by 2050. While modest growth makes stabilisation more likely, high convergence increases the absolute and relative economic burden on developing countries and increases reliance on future technologies like Carbon Capture and Storage (CCS).
